It's funny because I constantly get annoyed when I see "first try" comments on heroic bosses since the RNG is so terrible, but I honestly got this first try with this deck and that was even with a terrible misplay of prep -> shadowstep when I meant to use vanish.:/ Amazing deck 10/10 would replay this boss just for fun.

People who say the deck is garbage doesn't know how to play a mill deck. It works like a charm, though I did not use Sabotage or Cobra, I used another Betrayal and Mistress of Mixtures for healing myself. Good luck
